Application filed April 8, 1926. Serial No. 100.639.

This invention relates to oil burners and ledge 16. In the construction illustrated more especially to the wick-type. of burner there are four radially extending wings 18 adapted for use in stoves. and each of these is provi-ded with a. perlt is one of the ob'ects of the invention foration 20, adjacent the lower end thereof,
